SPECIFICATION formng-part of Letters Patent No. 223,848, dated January 27, 1880. Applicants filed April 29, 1879.

To all whom t 'may concern,

Be it known that I, WILLIAM E. HARRIS, of the city, county, and State ot' New York, have invented a new and useful Improvement in Pumps, which invention is fully described in the following specification, reference being had to the accompanying drawings, in which- Figure l is a front view of the pump, pressure-pipes, and plungers. Fig. 3 is a section in 1o the plane x x, Fig. 5. Fig. 4 is a section in the plane y y, Fig. 5. Fig.v 5 is a section in the planea e', Fig. 1. Fig. 2 is a front View, 4on a smaller scale, ot' the plunger and cylinders for working the secondary pump.

Similarletters indicate corresponding parts.

This invention relates chiefly to that class of pumps called mining-pumps,77 and itconsists in the combination ot' pressure-pipes, plungers working in said pressure-pipes, diszo charge-opening conneetingwith said pipes, pistons working in pressurecylinders and acted on by the columns of water in said pressure pipes, pressure cylinders, suction cylinders for receiving waste-water, and suctionpipes for conveying the waste-water into saidl suction-cylinders, all combined and operating as will be hereinafterdescribed; also, in the combination, in a pump, ot' pressure-pipes, plungers working' in said pressure-pipes, dis- -charge-ol'ieni'ng communicating' with the same, pistons acted on by the columns of Water in said pressure-pipes, pressure-cylinders, suction-cylinders, and suction-pipes, said suction-cylinders communicating with the press- 3 5 ure-pipes bysuitable valves, so that the wastewater from these suction-cylinders is forced into the pressure-pipes and discharged, these pipes thus taking the place of rising mains, as will be hereinafter set forth; also, in the 4o combination, in a pump, of pressure-pipes, plungers working in said pressure-pipes, discharge-openin g comn'iunicating with the same pistons acted on by the columns of Water in said pressure-pipes, pressurecylinders, suction-cylinders, and suction-pipes, said suctioncylinders communicating with the pressurepipes by suitable valves, so that the waste-water from these suction-cylin ders is forced intothe pressurepipes and discharged, whereby 5o these pressure-pipes are kept constantly full,

and unequal strain and injury to the mechanism are avoided; also, in a mining-pump constructed substantially as described,'and provided with a connecting-rod forimpartin g motion to a secondary pump, so that by the same motive power several mines can be pumped out simultaneously; also, in a mining-pump constructed substantially as described, and provided with two pressure-pipes, so that the column of water in one pressure-pipe assists in 6o 'raising the water in the other pressure-pipe, thus saving a large amount of motive power.V

In the drawings, the letters H H designate two pressure-pipes which reach from the surface ot' the earth down into the mine. In 65 these pressure-pipes Work two plungers, B B', alternately up and down. Motion is imparted to them by rods from any suitable motive power, as a steam-engine. E E are guides for keeping the plunger' in a right line. D D 7o are stung-boxes, through which the plun gers pass. These pressure-pipes H H are full ot' Water, and when the plunger B descends in the direction of the arrow it forces the water down through this pipe H and causes it to press on the lower end of the piston X, working in the cylinder W, forcing it up. This piston X passes through stung-boxes D D up into the suction-cylinder Y, and when it is pressed up it forces the water in said cylinder 8o Y through the valve T up into the other pressure-pipe, H. This piston Xis further connected, by a rod, s, to the piston @working in the suction-cylinder L and pressure-cylinder K, and when the piston X is forced up it also forces up said piston Q5. By this means the water in the top of the cylinder K is forced out through the T-connection I and up into the pressure-,pipe H. This action continues till the plungerI B is at its lowest point and 9o the piston B' is at 'its highest, when part of the water flows out at the discharge-opening F, because ofthe plunger B rising above said dischargeuopening. The piston Q, while being pushed up, also leaves a partial vacuumbelow it in the suction-cylinder L, whereby the valve lM is opened and water iiows in through the suction-pipe O, which reaches into the Water into the mine to be pumped out.

When bthe plunger B begins to descend the roo vIo 2 seas-.ls

Water in the pressure-pipe H' is forced down, and, closing the valve T, presses through the T-connection I on the top of the piston Q, forcing it down, togethcr with the piston X.

The water in the suction-cylinder L is acted on by the lower end of this piston Q, whereby the Valve M is closed, the valve R is opened, and the water forced into the pressure-pipe H. The water in the cylinder W7 is also forced outinto this pipe H by the descent of the piston X. This action coutumes until the plunger B has reached its highest point, when some of the water ilows out through the dischargeopening F. This discharge-opening F connects with both pipes Hand I '5 but, it' desired, a separate discharge can be provided for each pipe Hand H'. The descent of this piston X in the cylinder Y produces a partial vacuum therein, which causes the valveN to open and water to flow in through the suction-pipe P, which pipe passes into the waste-water in the mine, the same as the pipe O.

It will be seen that the pressure-pipes H H', which serve to impart motion to the pistons X Q, also receive the waste-water from the suction-cylindersYL and discharge the same at F. The advantage of this arrangement is that the pressure-pipes H H' are always kept full.

In other machines the pressure-pipes are merely used to impart motion to the pistons, while the waste-water is discharged through one or more rising mains. In these machines it often happens that by evaporation or leakagethe quantity ot' water in one pressure-cylinder becomes smaller than in the other. Unequal strain is thus thrown on different parts of the machinery. By my invention this inconvenience is entirely overcome.

It' it is desired to repair the pump, the water in the pressure-pipes H H' is prevented from flowing out by closing the stop-cocks Gr' G. To the piston X is attached a rod,j", which imparts motion to a piston, J, working in cylinders a. b. With these cylinders a I) connect pipes H" H", which are the exact counterparts of the pipes H and H', and connect with a pump in a mine situated farther down. This secondary pump is constructed like the pump shown in Fig. l, and the waste-water which discharges through these pipes H" H"' flows through the openings V V into a tank or other suitable receptacle situated in the same mine as the pump shown in Fig. l. From here the water is pumped by said pump (shown in Fig. l) up to the surface of the earth, and there discharged through opening F.

By this means several mines or several galleries of a mine which are at different levels can be pumped out simultaneously.

I am aware of English Patent No. 2,228 of 1863, and I hereby disclaim the construction and arrangement therein shown, as such are not my invention.

What I claim as new, and desire to secure by Letters Patent, is-

1.*The combination, in a mining-pump, of two parallel pressure-pipes, H H', two alternately-operating plungers, B B', working respectively in said pressure-pipes, a dischargepipe, F, coimecting with the said pressurepipes, a lower and upper pressure-cylinder, W and K, with which the pressure-pipes communicate, intermediate lower and upper suctioncylinders, Y and L, vcrtically-arranged pistons X and Q., connected together and arranged respectively in the lower and upper pressure-cylinders, and actuated by the columns of water in the pressure-pipes, all constructed and arranged for operation as herein shown and described.

2. The combination, in a pump, of .two pressure-pipes, H H', two plungers, B B', dischargeopening F, (one or more,) communicating with said pipes H H', vertically-armnged pistons X and Q, acted on by the column of water in said pressure-pipes, lower and upper pressurecylinders, W and K, intermediate upper and lower suction-cylinders, Y and L, and suctionpipes O and P, communicating, respectively, with the upper and lower suction-cylinders, said suction-cylinders Y and L communicating with the [messure-pipes H H' by suitable valves R and T, so that the waste-water from these suction-cylinders is forced into the pressure-pipes and discharged, these pipes thus taking the place of rising mains, substantially as set forth.

3. The combination, in apump, of two pressure-pipes, H H', two plungers, B B', dischargeopening F, (one or more,) vertically-arranged pistons X and Q, lower and upper pressurecylinders, IV and K, intermediate lower and upper suction-cylinders, Y and L, and suctionpipes O and P, communicating, respectively, with the lower and upper suction-cylinders, said suction-cylinders communicating with the pressure-pipes by suitable valves R and T, so that the waste-water from these suction-cylinders is forced into the pressure-pipes H H' and discharged, whereby these pressure-pipes are kept constantly full and unequal strain and injury to the mechanism are avoided, substantially as described.
